MACHINE FOR REMOVING AND APPLYING CROSS CHAINS.

Applicationfiled March 17, 1925. Serial No. 16,251.

To all-whom it may concern: Be it known that I, CLAom E. CoRsNrrz, a citizen of the United States, residing at Halifax, in the county of Dauphin and State of Pennsylvania, have invented certain new. and useful Improvements in Machines for This invention relates to an apparatus for removing and replacing cross chains of automobile anti-skid chains and more particularlyto a device having means for open- 1 mg or closing the end links of the cross cha ns tothereby remove. or apply them to side chains of the antiskidding device.

An important object of the invention is to provide a device ofthis character which may be very readily and cheaply produced, which will be durable and efficient in service and a general improvement in the art.

A further object of the invention is to provide a'device of this character embodying a foot operated reciprocable member which. coacts with a pair of anvils, one of. which is employed with the reciprocable member to open the link and the other of which is employed with the reciprocable member to close the link.

A furthervobjectof the invention is to provide a construction of this character in which one of the anvils affords ameans for supportingfthe other of the anvils and additionally a means for supporting the antiskid chain upon which the work is being done.

A still further object of the invention is to provide a device of this character of such structure that the hands of the operator are left free to guide the links of the chains to the anvils during the operation of opening or closing the links.

. These and other objects. I attain by the construction shown in the accompanying drawings, wherein for the purpose of illustration is shown a preferred emobdiment of my invention and wherein Figure 1 is a perspective view of a cross chain removing and applying device constructed in accordance with my invention;

Figure 2 is a side elevation thereof;

Figure 3 is a vertical sectional view through the upper end thereof;

Figure 4 is a perspective of the rear of the table removed; and

sion' 20.

Figure 5 is a detailed-perspective view showing the mannerof associating a link to V be removed=with the anvil 15. and exten- Referring now more particularly to the drawings, the numeral indicates a vertical standard adapted to be supportedwith its lower end 11 resting upon the floor or other suitable case. Secured-to the upper outer face ofthe standard is-a table 12 which is horizontally extending and which has a vertically disposed flange 13 which is bolted 'or .otherwise secured to the standard, as at 14.

The table is of greater widththan'the standard and at the projection atone side, the flange 13 has boltedthereto an anvil 15, the construction of which wilLhereinafter more fully appear.

That face of the table, 12 opposing the standard is formed in opposition to the standard with a notch 16. Depending from the outer or front wall of this slot is a flange 17 parallelingthe opposed face of the standard. Between this flange and the standard and between the opposed faces of below the table. This slide has a horizontal extension at its uper end, indicated at 19,

opposing the table and moving toward the table as the slide ismoved downwardly. At its npper end, it is also provided with a gooseneck extension 20, the end of which overlies and opposes the upper surface of the anvil in such relation that theinner face of the extension and the outer face of the anvil 15 are arranged in the same plane. The neck 20 and anvil 15 have oppositely beveled faces 21 and 22 forming upon this extension and upon the anvil pointed outer ends 23 and 2 1. Both the extension 20 and anvil 15 are knife-edged by beveling what is the outer face thereofwhen the anvil and the extenison are arranged in side to side relation as in Figure 2, these beveled faces being indicated at 25 and 26 respectively.

The lower end of the standard is provided with a pair of bearings 27 preferably arranged upon the rear face of the standard, these bearings supporting a shaft 28 extending through a notch 29 formed in the lower end of the standard. Mounted upon the shaft is a pedal lever 30 having a foot treadle 31. A rigid link 32 is engaged at :its lower end with the lever 30 at a point "the sections of the flange 13 is disposed for adjacent the front face of the standard and at its upper end with the slide 18. Secured to the treadle lever is a spring 33 normally maintaining the treadle and slide in elevated position.

In the use of the device for removing cross chains, the end link 34 of the cross chain which, as is well known to those familiar with the art, has an eye 35 clamped about the link of the side chain, is so placed upon the anvil 15 that the point 22 of this anvil enters the eye and this eye is vertically arranged. The treadle 31 is then operated to cause the slide to move downwardly and the point 23 of the extension 20 to likewise engage against the eye 35. Continued pressure will cause these two points to pass through the eye spreading the same sutficiently to permit the cross chain link to be disengaged from the side chain. When it is desired to secure the cross "chain link to the side chain, the side chain is arranged beneath the horizontal extension 19 and the cross link engaged therewith. The slide 18 is then moved downwardly and the extension 19 engages the free ends 36 of the eye and forces them downwardly until the link is firmly engaged with the side chain and unremovalole therefrom. During either of these operations, the skid chain is supported from the table 12 and the hands of the operator, which are not required in either operation to manipulate the machine, may be employed for steadying and guiding this chain.

Since the structure hereinbefore set forth is obviously capable of a considerable range of change and modification without materially departing from the spirit of my invention, I do not limit myselfto such specific structure except as hereinafter claimed.

I claim:

1. In a device for removing and applying the cross chains of automobile skid chains, 21 vertical standard, a table secured to the standard at the upper end thereof and combining with the vertical standard to provide a vertically disposed guide-way, a slide vertically reciprocable within the guide-way, a spring for retaining the slide in elevated position, a foot lever for shifting the slide downwardly, an anvil having a point for engagement in the eye of a chain link carried by the table, a goose-neck carried by the slide and extending over the anvil for engagement with the link toforce it against the pointed edge of the anvil as the slide is moved downwardly, and an angular portion carried by said slide overlying the table and adapted to coact with the table to compress therebetween the ends of an open link to thereby close the link.

2. In apparatus for removing and applying the cross chains of automobile skid chains, a vertical standard, a table secured to the standard at the upper end thereof and having a notch opposing the standard, the forward edge of the notch having a flange opposing the standard and combining with the standard to provide a slide guide, a slide vertically reciprocable within the guide, means for vertically reciprocating the slide, said slide having at its upper end an integral angular extension overlying the table and adapted to coact with the table to compress therebetween the ends of an open link to close the same, said slide having a further integral goose-neck extension having a pointed extremity and apointed anvil car ried by the table and with which the gooseneck coacts to open an engaged link.

In testimony whereof I hereunto afiix my signature.
